A novel lithiated tin vanadium oxide (LSVO) compound has been synthesized via straight-forward, simple, economical and scalable sol-gel method. Interpretation and indexing softwares have been used to predict the crystal structure system to be tetragonal. A preliminary test on Li-ion half cell with the configuration LSVO//Li using 1 M lithium hexafluorophosphate (LiPF6) in EC:DEC (v/v = ½) as electrolyte has shown reversible capacity of 211 mAh g-1 at the end of 53rd cycle when discharged at 1 V....


Li-ion batteries are currently the dominant energy storage device for high-energy applications, such as cell phones and laptops. However, in the context of sustainable development, the high cost and the relatively low energy density are difficult to meet the requirements of applications in the future. For example, electric vehicles require batteries with a lower cost and a higher energy density to reduce the cost and improve the driving range; and the development of renewable but intermittent en...

Ultrasonic synthetic method is used to prepare various nano-porous (nanofoam) metal current collectors, including, but not limited to, copper metal for anode and aluminum/nickel metal for cathode. The innovative nanofoam metal current collectors are used to prepare high performance lithium ion (Li-ion) battery, which shows good capacity retention and cycling stability even under fast charge/discharge rates. It is easy to be industrialized and can improve rapid charge/discharge rates and electroc...
